Have you searched the mailinglist archives ? I bet this has been asked before.
Anyway, see for example ShinyForm and its friends (in elephas) http://tinyurl.com/cuyugo For adding attribues, use AttributeAppender . ErrorHighlightBehavior from elephas : public class ErrorHighlightBehavior extends AttributeAppender { private static final long serialVersionUID = 1L; public ErrorHighlightBehavior() { super("class", true, new Model("error"), " "); } @Override public boolean isEnabled(Component component) { return !((FormComponent) component).isValid(); } Note: I have nothing to do with the elephas project, I just found some inspiration in their code. regards, Maarten On Sat, Apr 4, 2009 at 8:15 PM, Luther Baker <lutherba...@gmail.com> wrote: > I'd like to turn the background of a text input yellow - if it has errors. > > Is there a standard way to do this?
